Solid state portable cooler

India's National Physical Laboratory has developed a portable, solid state cooling technology that does not require the compressor or refrigerant found in conventional refrigerators. It can therefore run off a low-power supply of only 75 Watts DC, e.g. directly from solar photovoltaic cells and batteries. The cooler was developed for two principle applications:

1. as a low-cost refrigerator for rural populations to store food and provide affordable comfort

2. to compliment India’s immunization program for rural populations of children by storing vaccines at low temperatures for a long time.

With a long lifespan and needing little maintenance, the solid state cooler maintains 5 °C at an ambient temperature of 40 °C but can cool to -2 °C if required.

Woshapp

Through the Woshapp app, Woshapp takes the car wash to the car and reduces the amount of water needed for each wash. Woshapp’s goal is to revolutionize the way we clean cars using sustainable and environmentally friendly methods. On average it takes 1.5 hours to wash a car and in addition about 200 litres of water are consumed per wash. Woshapp service agents cycle to the car and carefully hand wash it in an environmentally friendly way, using only about 400 millilitres of water per wash, thereby saving 99% of the water consumed by a regular car wash. The method provides better quality than a mechanical car wash, avoiding the scratches that can occur.

Battery swapping for two-wheeler EVs in India

Batterypool's ecosystem also makes owning a two-wheeler EV 30% cheaper than its petrol counterpart. The battery swapping service is enabled by patent pending swap station hardware, product design, a small business retail model and an Internet-of-Things layer. India has the largest two-wheeler vehicle market in the world. Using this model Batterypool intends to drive the mass adoption of electric mobility among two-wheelers.

Small-scale decentralised upgrading of waste

Takachar developed technology at the Massachusetts Institute of Technology (MIT) and licensed it in order to develop small-scale, low-cost, portable biomass treatment systems that can be attached to the back of tractors, trailers, or even donkey carts. Takachar’s mobile biomass systems can then be deployed on farms in remote areas to take small pockets of biomass residues and process them onsite into a chemically densified form that is moisture-resistant and volumetrically dense. This can in turn reduce the logistical, collection, and disposal cost by about 75% compared to current alternatives such as baling and pelleting. Takachar therefore provides farmers with a cost-effective way to clear their land of crop residues rapidly after harvest.

Saathi’s mission is to create hygiene products that are good for the body, environment, and community. Saathi’s 100% biodegradable sanitary pad is made from an agricultural by-product, banana fibre, one of the most absorbent and abundant natural fibres in India. Unlike wood pulp or cotton, the raw materials for Saathi’s sanitary pads don’t require additional land. They also don’t contain any bleacher chemicals, thereby minimising skin irritation and the release of toxins into the environment upon disposal.

Insect based protein and natural commodities

Hexafly are developing new material sources for the aqua feed, chitin and plant nutrition industries from the sustainable farming of insects. In the next few years, Hexafly predicts that the exponential increase in demand for fish food will far exceed supply and the industry will not be able to meet this demand due to declining wild fish stocks, stricter fishing quotas and an increase in material costs. Hexafly’s aim is to bring an insect farming revolution to the world and find smart ways to feed the planet. Hexafly is also developing novel chitin extraction technologies. Chitin is a high-value bio-polymer with many uses in medicine, cosmetics and as a food additive.

Coolar

Coolar has produced an electricity-independent medical refrigerator. The Coolar system uses warm water that is heated through solar energy and stored in a water tank. It does not use any moving parts, hazardous cooling fluids or lubricants. Thus, the Coolar system is a cheap, durable and sustainable solution for storage of vaccines, medicines and food in regions with unreliable or expensive electricity. The Coolar system runs independently from electricity by using solar heat, which makes it almost carbon neutral. Such a refrigerator can enable doctors and health professionals to preserve lifesaving medicine and vaccines in a reliable and eco-friendly way.
